WASHING MACHINE.

Application filed October 15, 1923. Serial No. 668,545.

To all whom it may concern:

Be it known that I, JAY J. HOGAN, a citizen of the United States, residing at Erie, in

the county of Erie and State of Pennsyl vania, have invented new and useful Improvements in Washing Machines, of which the following is a specification.

Washing machines'have heretofore been. made of what might be termed the plunger type in which there are reciprocating eleinents acting as heaters upon the clothes.

' screws 24.

These devices are very eflicient washers in many respects but involve an uneven load thus requlring a comparatively large motor. The continuous rotary washers with which I am familiar have faults as to massing of the clothes and also do not in some instances involve sufficient agitation for rapid washing. With the present invention I combine the rotating and plunger types of washers, utilizing the desirable function of both with some added results.

The invention is illustrated in the accompanying drawing which shows a central section of a washin machine.

1 marks the tu 2 a stand on which the tub is mounted, 3 an electric motor mounted on the stand, 4 a drive shaft of the electric motor, 5 a gear fixed on the shaft 4, 6 a hearing for the shaft 4, the bearing being arranged in a housing 7 secured to the bot tom of the tub.

The gear 5 meshes with aheveled gear 8 fixed on a vertical shaft 9. The lower end of the shaft is journaled in a bearing 10 in the housing 7 and the upper end of the shaft extends through a bearing 11 secured to the bottom of the tub, the upper end of the shaft extending through the hearing.

A driver 12 1s fixed on theeupper end of the shaft by means of a pin 13. The driver is provided with ahearing 14 with an axis at an angle to the axis of the shaft v9. A shaft 15 1s journaled in the hearing 14 and locked therein by a collar 16, the collar being locked to the shaft by a set screw 17.

A conical head 18 is locked on the shaft 15 by a pin 19. A carrier 20 has a conical hub 21 which fits on the head 18 and is clamped thereon by a thumb nut 22 screwed on to the end of the shaft 15.

Beaters, preferably in the form of vacuum cups 23 are mounted on the carrier and as shown are secured to the carrier by cap The driver is preferably housed and the clothes spaced somewhat from the center by a housing made up of the upright cylinder 25 which is secured to the bottom of the tub and a telescoping housing 26 which is parried by the driver 12. This protects the clothes from the hearings and shields the bearings from the water of the tub.

In operating the washer, the clothes are arranged around the bottom of the tub with the usual level of water and the motor is ut in operation rotating the shaft 9 which rotates the driver 12. The engagement of the heaters 23 with the water and the material being washed retards the beater in engagement and causes the carrier to rotate relatively to the driver. In other words, it rolls around the space above the clothes as the driver is rotated. This rotation causes the heaters to roll into the water and into contact with the clothes thus depressing or beating them and as the cups are withdrawn or rolled up out of the water the pull of the cup tends to loosen and work the material. The pull incident to withdrawing the cups from the water is sustained by the downward thrust of the next ingoing cup so that there is a more or less balancing of pressures. The ingoing cups are slightly inclined forwardly and the driving force of these cups creates a surge which is retarted by the outgoing cup so that there is a very violent agitation both of the water and of the material due to the combined up and down, or in and out movement of the cups and the forward driving movement due to the rotation.

In order to adjust the cups to a greater or less quantity of material I prefer to adjust the height of the driver. This may be accomplished as follows: A spool 27 is fixed on t e shaft 9. This spool is engaged by an arm 28 fixed on a shaft 29. A lever 30 is fixed on the shaft 29 and operates over a segment 31. The lever may be secured in different positions by a. pin 32 operating in perforations 33 in the segment. By moving this lever the shaft 9 may he raised or 10v:- ered, thus raising or lowering the driver and adjusting the heaters to the quantity of material in the tub.

It will be noted that the cups or heaters are rigid with the carrier so that their position relative to the tub is maintained throughout the operation and there is no possibility of these beaters or cups engaging or striking the walls of the tub, and that the carrier has an orbital mounting with an axis at an angle to the axis of the driver. It will be noted also that the cups are in a plane of the center of oscillation. As a result the up and down movement of the cups is approximately in an arc nearly perpendicular and thus the cups operate in a smaller space and more nearly in a direction to exert a beating action rather than a rubbing action. It will also be observed that this center of oscillation is within the housing, the rotating cap of the housing protectin this part from the water, or suds of the tu What I claim as new is 1. In a washing machine, the combination of a tub; a beater carrier within the tub; a rotary driver"; an orbital mounting for the carrier driven by the driver and having its axis at an angle to the axis of the driver; and a plurality of beaters rigidly mounted on the carrier and adapted to be depressed and elevated by the orbital movement of the carrier.
